Rename files inside of archive. This command is supported for
RAR and ZIP formats. The command syntax is:

winrar rn <arcname> <srcname1> <destname1> …
<srcnameN> <destnameN>

For example, the following command:

WinRAR rn data.rar readme.txt readme.bak info.txt
info.bak

will rename readme.txt to readme.bak and info.txt to info.bak in
the archive data.rar.

It is allowed to use wildcards in the source and destination
names for simple name transformations like changing file
extensions. For example:

WinRAR rn data.rar *.txt *.bak

will rename all *.txt files to *.bak.

WinRAR does not check if the destination file name is already
present in the archive, so you need to be careful to avoid
duplicated names. It is especially important when using wildcards.
Such command is potentially dangerous, because a wrong wildcard may
corrupt all archived names.
